Abstract

Et hybridformingsparti (1) med dobbel dukfremstillingsmaskin er beskrevet hvor stigningen av dukbæreelementene (70), (71), (73), (72) avtar progressivt i maskinretningen, idet nivået av vakuum tilført formingsduken (2), (4) gjennom awanningskarene (53), (54), (10) og (55) avtar i maskinretningen, idet to formingsduker (2), (4) sammen med massen klemt mellom dem krysser minst fire separate og atskilte vakuumsoner innenfor formingspartiet når de fremskrider i maskinretningen, idet nivået av vakuum tilført minst den siste av minst fire separate og atskilte vakuumsoner er høyere enn vakuumnivået tilført den første av de separerte og atskilte vakuumsoner, idet nivået vakuum tilført de minst fire separate og atskilte vakuumsoner følger en valgt profil og awanningskarene (53),(54),(10) og (55) som bærer dukbæreelementene (70),(71),(73) og (72) er anordnet slik at dukbæreelementene (70),(71),(73),(72) er anbrakt i en vekslende sekvens for maskinsidene av begge formingsdukene (2), (4).
